[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] See Figures 1-10 The door reinforcement structure includes a door assembly, which includes an inner door panel 1 and an outer door panel 2. A reinforcing block 3 is provided between the inner door panel 1 and the outer door panel 2 to support the door assembly. The reinforcing blocks 3 are respectively provided on the left and right sides of the door assembly. The inner door panel 1 and the outer door panel 2 are connected by the reinforcing blocks 3.

[0028] A cavity 4 is formed between the inner door panel 1 and the outer door panel 2, and a reinforcing block 3 is placed in the cavity 4 to provide support for the door assembly.

[0029] The reinforcing block 3 is provided with several reinforcing ribs 5, which are distributed at intervals on the reinforcing block 3. The reinforcing ribs 5 can improve the structural strength of the reinforcing block 3, thereby improving the supporting strength of the reinforcing block 3 for the door assembly.

[0030] The reinforcing block 3 is provided with a reinforcing boss 6, and the left and right sides of the outer door panel 2 are respectively provided with flange grooves 7. The reinforcing boss 6 is positioned in the flange grooves 7 so that the reinforcing block 3 is positioned on the outer door panel 2.

[0032] The reinforced boss 6 is hollow and has a buckle 8. The first flange 22 has a snap-fit ​​hole 9. The buckle 8 and the snap-fit ​​hole 9 snap together to fix the reinforcing block 3 to the outer door panel 2. Because the reinforced boss 6 is hollow, the buckle 8 can be elastically deformed, thereby preventing the buckle 8 from jamming with the snap-fit ​​hole 9 when they snap together.

[0033] The inner door panel 1 has a second flange 23 on both the left and right sides.

[0034] The second flange 23 is provided with a first fixing hole 10, the first flange 22 is provided with a second fixing hole 11, the reinforcing boss 6 is provided with a fixing post hole 12, and the first fastener 13 (screw) passes through the first fixing hole 10 and the second fixing hole 11 in sequence and is then fastened to the fixing post hole 12 to connect the inner door panel 1, the outer door panel 2 and the reinforcing block 3.

[0035] The bottom of the reinforcing block 3 is provided with a positioning boss 14, and the bottom left and right sides of the outer door panel 2 are respectively provided with first positioning holes 15. The positioning boss 14 passes through the first positioning holes 15 so that the reinforcing block 3 is positioned on the outer door panel 2.

[0036] Hinges are provided on the left and right sides of the bottom of the door assembly. The hinge assembly includes a first hinge plate 16 and a second hinge plate 17 that are hinged to each other. The first hinge plate 16 and the second hinge plate 17 are hinged to each other through a hinge shaft 24. The first hinge plate 16 is fixed to the door assembly. A positioning rib 18 is provided on the reinforcing block 3. A second positioning hole 19 is provided on the first hinge plate 16. The positioning rib 18 passes through the second positioning hole 19 to position the first hinge plate 16 on the door assembly, which facilitates the installation of the first hinge plate 16. The reinforcing block 3 is located at the bottom of the door assembly. The reinforcing block 3 can also improve the structural strength of the hinge mounting point of the door assembly. The second hinge plate 17 is fixed to the inner tub of the dishwasher.

[0037] The second flange 23 is provided with a third fixing hole 25, and the first hinge plate 16 is provided with a fourth fixing hole 26. The second fastener 27 (screw) passes through the third fixing hole 25 and is fastened to the fourth fixing hole 26 so that the first hinge plate 16 is fixed on the inner door panel 1.

[0038] A recessed platform 20 is provided on the reinforcing block 3, and an inwardly bent portion 21 is provided on the first hinge plate 16. The bent portion 21 is provided on the recessed platform 20 and abuts against the bottom wall of the recessed platform 20. The recessed platform 20 is used to avoid the first hinge plate 16 and can also position the first hinge plate 16. The positioning rib 18 is provided on the recessed platform 20.

[0039] This dishwasher includes a door reinforcement structure and an inner tub, with the door assembly located on the front side of the inner tub.
